Undo Doesn't work in Unity 3.4?

As the title suggests,

My undo doesn’t work?

My undo works fine.

Humm, seems to be working now - all I did was restart computer >_< !

I second this. My undo works as well.

Check to make sure your “Play” button is not pressed, I had the same issue with undo greyed out after pressing it & forgot to go back to the edit mode.

This person has the answer :slight_smile:

Close the asset store window and restart unity. It’s a bug.
